- from the cross head E can beprovided to actuate the two scavenging air pumps.

I claim 1. A vertical two stroke cycle internal combustion engine of a plurality of spaced cylinders and associated cross-heads, scavenging air pumps comprising cylinders disposed adjacent to, and partly within the spaces between said s aced cylinders, and means for actuating ad acent scavenging air pumps by the cross-head of the cylinder between them.

2. A vertical two stroke cycle internal combustion engine of a plurality of spaced cylinders and associated cross-heads, scavenging air pumps comprising cylinders disposed adjacent to, and partly within the s aces be tween said spaced cylinders, and a -shaped arm connected to the cross-head of a cylinder intermediate two of said pumps adapted to actuate said pumps.
